This invention relates to a new and useful improvement in paper bottles and containers and. in particular, to a bottle made from heavy paper or light board stock having a body which is square,

in cross-section, a bottom integral therewith and raised somewhat above the bottom edge, and a neck projecting from the upper edge of the body which gradually tapers and approaches a round cross-section which it acquires at its upper end and which may be enveloped by an annular lip of a size adapted to receive any. standard cap such as that used for closingglass milk bottles for example.

The essential features embodied in this invenbottle made from an integral sheet having a body a part rectangular in cross-section with comers stiffened by integral vertical beads or ribs a neck part rectangular in cross-section at the bottle shoulder and tapering into a circular formation at the mouth, the change fromrectangular to circular formation being accomplished by form- Figure 4 is a vertical cross section of the bottle on the line 4-5 oiFigure 2 viewed as indicated by the arrows;

As shown in Figure 11 the blank I from which the bottle is made consists of a flat piece of heavy bottom part consisting of four plies of paper 'so folded within the body part to form a recessed bottom and a two-ply rim or chimb. The mouth of the bottle is provided with a lip or rim preferably in the form of a double flanged metal ring- I attached and secured in a novel way which insures absolute security and freedom from 1eak-.

age.

Since one of the important uses of this bottle is as a container for milk, the form selected for illustrationin the drawing hereof and for description herein, is designed particularly for that equipment with which most dairies arernow equipped can be used without alteration. However, it will be understood, that the invention is.

not limited to a bottle for this purpose or to the actual or relative dimensions shown.

In the drawings- Figure l is a side elevation of the bottle com- 'service so that standard filling and capping paper or light board divided into four identical panels '2, 3, a and 5 by vertical scores 6 impressed from the side of the blank which becomesthe inner side of the bottle, which is the side shown in Figure 11, so that they form outwardly-pro-.

jectingribs similar to that shown in Figure 13.

Beginning at the point I, which is the junction.

between the. body and the neck of the bottle, panels 2, 3, 3 and 5 taper symmetrically to the top of the blank, the taper being such that when th neck is formed the edges 8 and 9 of adjacent panels will meet throughouttheir length. Beyond the outer edge of one of the outer Panels (5, for example) is a flap N which, when the bottle is formed, overlaps the outer edge of the opposite panel 2 and is tightly secured thereto by a suitable adhesive. l

The tapering neck portions of panels 2, 3, t

and 5 are connected together and also the equivv alent portion of flap i0 is connected to the earljacent edge of panel'5 by integral sections ll through which scoring 8 is extended and which is also provided with additional scorings l2 and I3, impressed from th face of the blank (the underside as viewed in Figure 11) and following the edges of the panels from the point i at which the neck begins to the top. Between these scorings I2 and Ills an additional pair of scorings l4 and I5 impressed from the back of the blank (the side shown in Figure 11) which start at a point l8 slightly above point I and diverge symmetrically with respect to scoring 6 and scorings l2 and i3. Sections II project uniformly, and preferably as shown, above the upper edges of panels 2-5 so that when the bottle is formed the upperedges of the folds formed by scores l 2- -l5 will be in alignment with the top edges of panels I5 and form a level seat for the neck ring.

, At the line II, which is to form the bottom edge or chimb of the bottle, panels 2-5 are crossed by a transverse scoring ll impressed from the back or inside of the blank. Below these are four additional scorings "-42 impressed irom the face or outside of the blank which denote an edge of each of the plies of which the depressed bottom of the bottle is made. Each of these scorings is parallel to scoring I8, but scorlugs 20, 2| and 22 are progressively nearer to scoring 18 by the thickness of the paper or board stock from which the blank is made.

' Below scorings l822 are four flaps 2326, which will constitute the four-ply bottom of the bottle. Of these flap 23-. which will form the inside ply, is the longest and of the same dimensions as the inside of the bottle at the bottom andlies in exact alinement with panel 2. Flap 24 s shorter by the thickness of the paper or board and the flaps 25 and 25 are progressively shorter, each by the thickness of the paper or board stock, and they lie below and in alinement with the panels 3, 4 and 5, respectively, withthe exception that edges 21, 28 and 29 are offset inwardly with respect to the corresponding edges 6 of the panels by the thickness of the paper stock. The other or right-hand edge of each of flaps 24 and 25 is in line with the corresponding edge of panels 3 and 4. The other edge 30 of flap 2615 also inset with respect to thecorresponding edge of panel I by the thickness of the stock.

From the blank the bottles may be made as follows: The blank is folded upon scorings 8 around -a mandrel corresponding in size and shape to the inside of the bottle and flap I0 is folded over the outer edge of panel 2 and securely attached there- 'will flll the entire space.

ing and similarly pushed bodily-into the end of the tube until it rests against flap 23 when it The third flap is treated in a similar manner and followed by the fourth flap 2B. Each flap is ecuredto contiguous flaps by a suitable adhesive with the result that a solid four-ply liquid-tight bottom is formed slightly above the'two-ply bottom edge or chimb of the bottle formed by webs 3|, as indicated in Figures 4 and 5, which edge coincides with scoring l8 and, consequently, lies in the same plane throughout.

The next step is to form the neck of the bottle. This is done by bending panels 2, 3, 4 and 5 inwardly until edges 8 and 9 of corresponding panels meet each other. In doing this the fan-shaped pleating sections l I will assume a pyramidal shape upon scorings I 2, l3, l4, l5 and '6 in the manner shown in Figure 9, after which the pleats are filattenedby pressure into the rib shown in Figure It will be noted from Figures 5, 9 and 10 that the inside of the neck of the bottle consists entirely of the panels 2, 3, 4 and 5, and that the edges 8-9 of these-panels meet throughout the length of the neck and are overlaid by the integral flattened pleats. Thus the surface of the inside of the neck is substantially smooth and unbroken and the junctionlines between adiacent panel will be automatically sealed when the bottle is coated with paraflin or subjected to any other similar coating process. In any event square at its lower end to acircle at its upper (Figures 8 and 14) along each edge which wil greatly stiffen the corners. I

The next step is preferably to form the bottom. This is done by folding flap Zlupon scoring l9 so that it covers the lower end of the tube already formed and then pushing it bodily into the end of the tube until scoring I8 is reached, as shown in Figure 12; This depresses the inside ply 23 of the bottom into the tube to the extent of the width between scorings. l8 and i9. This flap will then fit exactly the bottom end of the bottle a little above its edge, as best shown in Figure 12, the connecting portion 3| between it and panel 2 lying snugly against the panel.

. 'The presence of portion 3| reduces one dimension of the space immediately below flap 23 by the thickness of the paper stock, but this has been provided for in the dimensions and positioning of flap 24, which can now be similarly bent on scoredge.

' manently retained by any desired sort of rim, but

the rim 32 illustrated in Figures 6 and 7 has been found highly satisfactory both with regard to the neck and its adaptability for receiving the combined capand hood illustrated. This rim consists of a circular metal channel, the outer flange 33 of which is longer than the inner flange 34. This is pressed over the edge of the neck of the bottle, including the pleats, and the edges of both flanges are curved towards each other as shown in Figures 6 and -'7. \Since the outer edge 35 of the rim is below the inner edge 36 the bottle neck is offset outwardly as shown, and is securely clinched between the edges and sides of the rim. The connection thus made is not only mechanically secure, but liquid tight.

The form of closure shown is a combined cap and hood, which consists of a cap portion 31 of a diameter slightly larger than the internal diameter of rim 32. so that when inserted it will flt securely under the shoulder formed by the curved inner edge 36 of the rim. From this cap portion 31 the hood portion 38 extends upwardly and then curves downwardly to form an apron 39, as shown in Figure 6, to envelope the rim.

- If desired, the lower edge 40 of apron 39 portion tents of the bottle when the cap is removed as will almost inevitably happen where a simple disk-like cap is used.

The four-ply construction of the bottom of this bottle not only eliminates all possibility of sagging, but also greatly stiffens the entire body.

The body of the bottle is further stiifened by the ribs Ba extending longitudinally along each edge, and the neck of the bottle is stifiened by reason of the pleats being erected from the four corners and also by the metal rim, with the result that an extremely sturdy and rigid bottle is produced capable of holding any ordinary liquid without material bulging, or other distortion. Furthermore, this bottle being square in cross-section has the great advantage of occupying much less space than a round bottle of equivalent height and capacity and is also very inexpensive to manufacture because of the materials employed and thesimple manufacturing operations required. Since a bottle of this sort is usually coated with paraflin or other coating, the edges of the neck panels will be sealed as already described, and also the edges of the inside ply of the bottom so that its inherent liquid tightness is supplemented and the interior isolated from the other parts as completely as in a glass bottle.

The stippled surfaces shown in Figures 11 and 12 represent those to which adhesive may be applied most advantageously, but it will be understood that this may be varied if desired. The

. adhesive may be a wet adhesive applied before the blank is folded or may be a plastic the adhesive properties of which are realized by the subsequent application of heat and pressure.-
